RangeError: The precision is out of range (Edge)
RangeError: precision {0} out of range (Firefox)
RangeError: toExponential() argument must be between 0 and 20 (Chrome)
RangeError: toFixed() digits argument must be between 0 and 20 (Chrome)
RangeError: toPrecision() argument must be between 1 and 21 (Chrome)

Error Type:

RangeError

        var el_down = document.getElementById("GFG_DOWN");
        function Geeks() {
            try {
                3.54.toFixed(-100);
                el_down.innerHTML = "'Precision out of range'"
                        + " error has not occurred";
            } catch (e) {
